Oslo is the most expensive European city to buy Facebook advertising, according to analysis from marketing software firm Kenshoo.
Taking record of the social network’s suggested bids to target users in specific cities, Kenshoo noted that factors such as the location and advertising demand caused fluctuations in the valuation of the slots throughout the continent.
For Newsfeed placements on desktop and mobile, Olso ranked the most expensive city at $0.73 a click-through. In second place was Vatican City at $0.70, followed by Helsinki ($0.57), Berlin (0.54) and Bern (0.53).
London was ranked ninth - costing $0.48 per conversion. On the other hand the most inexpensive cities to advertise were Skopje in the Republic of Macedonia, Sarajevo in Bosnia and Herzegovinia and Podgorica in Montenegro.
The volume of each city population using Facebook, crossed with their affluence and the demand for ads, were all major drivers of cost.
